Replace your cooling fan motor relay because if you dont eventually your radiator will explode and this will cause your engine block to crack and then if your fan isn't blowing the engine will continue to overheat and the engine will seize and then you need a new engine. A cooling fan motor relay is around $30.

Overheated. Why won't it start?


I'm not really familiar with JEEP mechanics but if you've replaced your water pump and it's still overheating with full water/coolant level, you should check the thermostat; when it fails, it's a common cause or overheating in all kind of cars

Did you bleed all air from the system? Is it actually overheating or is the light just coming on? If so, replace the temperature sending unit. If you are loosing coolant with no apparent leak then suspect a blown head gasket which will cause the engine to overheat. A compression test will verify this.

I have a 2000 Jeep Grand Cherokee Limited, V-8. Yesterday, I was driving and it started overheating. Reserve and radiator were both full with antifreeze. We replaced the thermostat and still overheats. ...


check for blockages in the piping, this may be blocking the flow of the antifreeze.
Also check the coolant you are using it needs to be a 50-50 ratio of coolant and water in most cases. Please go by the manual.

Doesn't sound as though you have overheating issues.
With a 196 thermostat, a vehicle is designed to run at 200 to 210,and you were putting it under a load on your trip.
I don't know why you would think about changing anything,unless you were doing some trouble shooting, and a test you were performing, indicated a failed component.
I would change the thermostat, as preventative maintainance every five years, and watch for the fans to be working after a trip of five miles or so.
Your A/C may have been switched off, by the various computer systems, to prevent overheating, or it may be starting to have it's own issues.

How do you replace the fan motor in '03 jeep grand cherokee laredo? - the damn thing overheats when idle - changed the relay & coolant sensor... still overheating


When was the last coolant change?
Under 2 years or 24,000 miles.

Change the thermostat and gasket first.

Use a 195F with pop-let protection.

A stuck/failing thermostat is a common cause of over-heating problem.

======
To change the fan,the entire protector plastic has to come out.

Most likely you will break the push in locking pins.

Get few replacement push in locking pins before you start the job.

2000 grand cherokee overheating heater blowing out cold air


Generally this condition is the result of coolant loss, or failed thermostat. If coolant goes below cylinder head level, or thermostat remains closed,heat will stop working. Do not drive with this condition as excessive heat buildup in cylinder head can and will do serious damage to heads and or head gasket.
Find out where leak is and correct it. Change thermostat as it may also be damaged. Check for excessive steam from tailpipe or miss in engine, as these symptoms indicate a cylinder head problem.
